The evaluation of the performance of an integrated bioreactor was carried out using organic municipal waste as the substrate. The test rig of the coupled bioreactor was designed and fabricated for experimented studies of anaerobic digestion of organic fraction of municipal waste. The first module up-flow bioreactor (UASB), has volume of 76 liter, the second module which was designed as twin in bioreactor with central dispensing unit has a total void volume of 76 liters. The test rig has a control panel which can be switch off and on from the experiment the maximum biogas yield was obtained in OLR3 module 11 with 1577 ml/stp followed by OLR1 module 1 with 1572 ml/stp. The least was noticed from the twin reactor OLR2 module 11 with 895 ml/stp. The accumulative biogas yield and R-values obtained show close agreement between observed and theoretical postulate.
